Abstract: (Elsevier)

The unusual properties of the X(3872) have led to speculation that it is a weakly bound state of mesons, chiefly D0D¯0* . Tests of this hypothesis are investigated and it is proposed that measuring the 3πJ/ψ , γJ/ψ , γψ′ , K¯K* , and πρ decay modes of the X will serve as a definitive diagnostic of the molecule hypothesis.
